A person who ‘passed gas’ on an American Airlines plane on Sunday afternoon forced all the passengers off the jet officials said.
The flight which was left unidentified by officials, was forced to land after passengers became ill with nausea and headaches due
to the incredibly stinky fart gas–It was later determined that he who smelt it had not necessarily dealt it. Linky:  www.charlotteobserver.com/news/local/article161691703.html
